T/XJBX 0191-2026 Emergency Response and Recovery Guidelines for Sudden Failures in Broadcast and Television Transmission and Transmission

Scope

The broadcasting and television transmission and broadcasting system undertakes important responsibilities such as disseminating party and government information, providing public services, and conducting emergency broadcasting. It is characterized by a wide coverage range, high requirements for continuous operation, and strong external impact of failures. The transmission and broadcasting chain typically consists of multiple subsystems including signal acquisition and aggregation, program encoding and multiplexing, transmission bearer networks, transmitters and antenna systems, power supply and environmental protection, monitoring and control platforms, etc. Any sudden failure in any link may lead to program interruptions, audio-visual abnormalities, coverage decline, erroneous or missed broadcasts, and security and compliance risks, which may affect social stability and public interests. Under the influence of extreme weather such as lightning and snowstorms, power fluctuations, equipment aging, software failures, link interruptions, cyberattacks, and human errors, sudden failures are characterized by sudden occurrence, complex location, short response windows, and high recovery pressure. At present, various units face problems such as inconsistent response procedures, disjointed process connections, and incomplete evidence records in aspects including emergency plan preparation, fault classification and response, command and coordination, on-site handling procedures, spare parts and equipment management, recovery verification, and improvement review, which hinder the efficiency of emergency response and the quality of recovery. To standardize the emergency response and recovery work for sudden failures in broadcasting and television transmission and broadcasting systems, this document proposes unified requirements around fault classification and response mechanisms, monitoring and alerting processes, emergency command and coordination, typical fault handling te
